The Techfine inverter converts battery power into alternating current with a pure sine wave, suitable for sensitive electronic devices. It supports lead-acid and lithium batteries and allows you to select the charging current according to the application. It can send a signal to automatically start a generator when the battery level is low and features AVR for voltage stabilization.
